Title: Wafer aligner in center of front end frame of vacuum system
Inventor: OTWELL ROBERT
IPC: H01L21/00
Filed: 1998-12-29
Granted: 2000-09-21
Abstract: A vacuum processing system has a wafer handling chamber, such as a mini-environment, for moving wafers therethrough. The wafer handling chamber has a wafer aligner, or orienter, for aligning the wafers according to the requirements of a process that the wafer is to undergo in the system. The wafer aligner is disposed at a location in the wafer handling chamber to minimize the number of movements that the wafer makes as it passes through the wafer handling chamber, to minimize interference between wafer handlers, or robots, when more than one wafer handler is used in the wafer handling chamber and to minimize the footprint area of the system. The presence of the wafer aligner in the wafer handling chamber eliminates the need to provide a separate wafer aligning chamber in the system.

Title: Method of forming transparent contacts to a p-type GaN layer
Inventor: LUDOWISE MICHAEL J
IPC: H01S5/323
Filed: 2000-06-07
Granted: 2002-01-01
Abstract: A method of forming a light-transmissive contact on a p-type Galliun nitride (GaN) layer (20) of an optoelectronic device (10) includes in one embodiment, introducing a selected metal (24) in an oxidized condition, rather than oxidizing the metal only after it has been deposited on the surface of the p-type GaN layer. In some applications, the oxidized metal provides sufficient lateral conductivity to eliminate the conventional requirement of a second highly conductive contact metal, such as gold. If the second contact metal (38) is desired, an anneal (40) in an oxygen-free environment is performed after deposition of the second layer. The anneal causes the second metal to penetrate the oxidized metal and to fuse to the surface of the p-type GaN layer. Ina second embodiment, the oxidation occurs only after at least one of the two metals is deposited in the surface of the p-type GaN layer. In one application of the second embodiment, the two metals are deposited and the oxidation occurs in an environment that includes both water vapor and oxygen gas (52). In an alternative application of the second embodiment, the first metallic layer is deposited and then oxidized throughout its depth. The second material, such as gold, is evaporated on the first material and a re-anneal step is performed to drive the second metal through the oxidized first metal. In any of the applications of either embodiment, a pattern of windows may be formed in the resulting contact structure or in additional layers that are formed thereon.
